Soldered Joints of Piezoelectric Products

Abstract

The paper considers issues related to the use of capillary luminescent flaw detection for monitoring glass-metal soldered joints of piezoelectric products. Standard methods of leakproofness testing of piezoelectric products are analysed; the framework for the applicability of each of them at the stages of the life cycle of piezoelectric products
is established. Based on the results of the studies, a capillary luminescent control method was chosen to check the tightness of glass-metal soldered joints in piezoelectric products. The stages of conducting a capillary luminescent method for monitoring glass-metal soldered joints of piezoelectric products are presented. A method for monitoring the tightness of piezoelectric products using the capillary luminescent method has been developed.
